Rent & eviction protection

Is 1591-1593 9Th Ave rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1939

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The property at 1591-1593 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-unit multi-family residential building constructed in 1939, featuring two stories and classified as a Flats & Duplex building. The most pressing current issues involve active building violations from February 2023, alleging unauthorized modifications including an unpermitted second dwelling unit on the ground level, unapproved wiring, plumbing work, and inadequate fire safety measures. These violations also cite concerns about improper occupancy and safety code non-compliance. A tenant complaint from February 2023 reported multiple serious concerns, including lack of central heating since October 2022, electrical issues affecting appliance functionality, and a rodent infestation, suggesting maintenance and habitability problems. Additional violations from March 2023 addressed fire safety (missing fire extinguisher) and sanitation issues.

The building's improvement history shows some significant renovations, particularly in 2015 when Unit 1 on the second floor underwent bathroom remodels and closet modifications, with corresponding electrical and plumbing work totaling $28,000. Earlier modifications from 1999 involved substantial basement improvements including multiple bathrooms, laundry areas, a game room, and garage door modifications. The property has experienced recurring issues with unauthorized modifications, as evidenced by an active complaint from 2018 regarding unpermitted remodeling work. A previous illegal short-term rental operation at the property was shut down due to building complaints, and there have been various maintenance issues reported through 311 calls, primarily related to graffiti and street cleaning matters in the surrounding area. The combination of active building violations, maintenance complaints, and unauthorized modifications suggests ongoing regulatory and habitability challenges at this property.

Risk rating

How 1591-1593 9Th Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
11thpercentile

Out of 1493 buildings in this neighborhood, 1329 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
